Ringer Speed

Hello all.


I'm currently working with a few Polycom phones connected to an Asterisk 13.23.1 server.  The Polycoms are


VVX 601

VVX 500

IP 501


The ringer speed problem is happening on the VVX series phones, Software version is: on the VVX phones


I'm using FTP for provisioning and the sip.cfg saf.x="" xml option to load wav files that I found on the Asterisk wiki many years ago.  In this case, merlin2.wav


The format of said audio file is, according to Audacity:


mono, 8000hz, 32bit float


The problem is, when a call comes into the phone, the initial ring is fine, but subsequent rings, the audio file is sped up.  Maybe a 1 second pause between playing the audio file. 


On the Polycom IP 501, playing the same audio file, there is around a 3 second pause.  Thinking that I could lengthen the merlin2.wav file, I tacked on a few seconds additional silence at the end.

When testing, the first play of the audio, with the extra pading, is a bit longer, but subsequent plays are right back to the super fast playback.


Is there an XML entry in the configuration that controls the timing between rings or is my wav file broken?

Hello @lti_support,


welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

As a reminder the basic information asked for:

  • Provide the Phone Model
  • Provide the Call Platform (aka openSIP,Skype for Business Online, Skype for Business on Premise, Lync)
  • Additional Polycom Infrastructure (RPRM,PDMS or BToE)
  • If applicable provide a backup of the phone in question

UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.

It would have been helpful to attach some of the configuration you mention as the volunteers could look at it.

Re: Ringer Speed

Moving to did not resolve the issue.


But, locating several VVX based ringtones that other have generated, show that the wave form for those ringtones also included a silence the same length of the audio.


So, I used Audacity to include such a silence length to the merlin2.wav file and all seems to be good.
